Where fdisk has gone from Debian Buster installation?

[qfu38]

For some reason there is no fdisk in /sbin or /usr/sbin while using debian 10 installation shell.
Is is a bug or somewhat?

[sickpig]

Code: Select all

root@s:~# which fdisk
/usr/sbin/fdisk

https://packages.debian.org/buster/fdisk

[peer]

on debian testing:

which fdisk
no output

whereis fdisk
fdisk: /usr/sbin/fdisk /usr/share/man/man8/fdisk.8.gz

[cuckooflew]

'which fdisk' must be run using sudo or su - as you can see below, when I run it as a normal user it returns nothing, this is because the command is not available to a normal user.
I seem to have it,.

Code: Select all

cuckoo@debian:~$ which fdisk
cuckoo@debian:~$
cuckoo@debian:~$ su -
Password:

root@debian:~# which fdisk
/usr/sbin/fdisk
root@debian:~# exit

But, ok, this is Debian SID (bullseye) but it was installed with debian 10 installer, and the upgraded:

Code: Select all

@debian:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description:    Debian GNU/Linux bullseye/sid
Release:        testing
Codename:       bullseye

This is more for a example, so the OP knows what output to show, and how...if indeed it is missing from the installer , then a bug report should be submitted. I did see when I searched some bug reports for this on Debian 9, but they said it was fixed, we are just debian users, and this should be reported to the developers, not much anyone here can do.
Also include exactly which instillation image you are using.

Yes, you must have administrator permissions to run 'fdisk'.

russel@DESKTOP-CK0E8I6:~$ fdisk -l
bash: fdisk: command not found

You don't need administrator permissions for 'which'.

Code: Select all

russel@DESKTOP-CK0E8I6:~$ which which

Just tried running 'fdisk -l' using the Debian 10 netinstall image, and rescue mode, it does have fdisk, :

So we need to know which image specifically, but I suspect it is simply the OP is not doing something correctly.

[p.H]

Please guys, pay attention.

while using debian 10 installation shell

This is about the fdisk-udeb installer component in the Debian installer context, not the fdisk command in an installed system context.

The fdisk-udeb installer component which provides fdisk in the Debian installer is still available. However I noticed that it is not installed by default any more in the 10.4 installer. If you want to install it, you can either :
- start the installation with "expert install" in the boot menu and select "fdisk-udeb" in the "load installer components from CD" stage.
- go back to the installer main menu at any time, select "change debconf priority" and lower the priority to "medium" or "low", then go back to the main menu, select "load installer components from CD" and select "fdisk-udeb".
- drop to a shell and run

Code: Select all

anna-install fdisk-udeb

Oops! I totally missed that. Thanks for pointing it out!

[cuckooflew]

Well, the OP is not clear on which version of the installer they are using, but also I am confused a little (nothing new, ) but, any way it does seem to be there, or is this not the same installer ?

=================================================

The above is using: https://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-10.4.0-amd64-netinst.iso

[p.H]

This is rescue mode. It installs more components by default than install mode, including fdisk and parted.

[cuckooflew]

Thanks, for clarifying
I was wondering about that,

P.H.If you want to install it, you can either :
- start the installation with "expert install"

Ok, maybe it is a different installer , I don't see any option for "expert install",... mine does show "advanced options", Is that the same, or what you mean ?
Next, ahh, never mind, "advaced options"> "expert install", I see it now, and then the

select "fdisk-udeb" in the "load installer components from CD" stage

Thanks P.H. That is interesting, I had never used or tried the "expert install", since I am not what I would consider a expert, so now I learned something new today.
Looks like the same shell:

So any way , fdisk is available, during the install.

[qfu38]

anna-install fdisk-udeb works for me, thank you

[p.H]

"Expert install" is not reserved to experts. It just asks extra questions. If you don't know what to answer, just leave the default answer. This is actually what the normal install does, without asking.

Here are couple of other commands available in the installer shell which I find useful :

- apt-install <package> allows to install a normal package (not udeb) in the installed system.
- in-target [--pass-stdout] <command> allows to run a command in the installed system. Standard output and error are sent to the installer log (/var/log/syslog and tty4). The option --pass-stdout sends the standard output to the terminal (but not the standard error).

For instance they allow to install the GRUB boot loader with special parameters not supported by the installer.

- apt-install <package> allows to install a normal package (not udeb) in the installed system.

A slight typo, should be:

Code: Select all

apt install

[p.H]

Not a typo.
Please guys, pay attention again.

This is about the Debian installer environement, not the installed system environment. apt is not available in the installer.
